Matsya Purana — Genealogy and Classification of Sacred Fires
पावकं पवमानं च शुचिरग्निश्च यः स्मृतः निर्मथ्यः पवमानो ऽग्निर् वैद्युतः पावकात्मजः //
pāvakaṃ pavamānaṃ ca śuciragniśca yaḥ smṛtaḥ nirmathyaḥ pavamāno 'gnir vaidyutaḥ pāvakātmajaḥ //
He is remembered as Pāvaka, as Pavamāna, and as Śuci-Agni, the pure Fire. The fire produced by churning (nirmanthya) is called Pavamāna, while the lightning-born fire (vaidyuta) is said to be the son of Pāvaka.
It does not discuss Pralaya directly; it classifies manifestations of Agni—especially churning-born and lightning-born fire—used in sacred contexts that uphold cosmic order (ṛta).
It supports dharma through correct ritual practice: a king or householder who sponsors yajña, consecrations, or domestic rites must employ properly generated and understood fires (e.g., arani-churned fire) to ensure purity and efficacy.
Ritually, it distinguishes the legitimate sources/forms of sacred fire—especially the nirmathya (churned) fire—commonly required for consecration, purification, and temple/altar rites described in Vastu and ritual manuals.
